组合导航具有高精度抗干扰的特点使其应用领域不断拓展，但由于其结合了卫星导航和惯性导航2类技术体制，传统单一测试手段难以对其进行科学全面的测试评估，需要针对组合导航技术的特点进行针对性的研究。据此，通过对组合导航机理的分析，提出了能够对组合导航进行兼容测试评估的方法，探索设计了基于模拟器的组合导航测试评估系统并进行了仿真验证。对实验模拟系统基本架构进行分析，利用该系统进行仿真实验，实验结果表明，本模拟器能够对模拟的加速度50 g、速度8 km／s的高动态载体性能进行很好的评估，与实际测试相比相差无几，该模拟系统可对组合导航终端的测试提供参考价值。

The application domain of GNSS/INS integrated navigation system is continuously expanded due to its high-precision anti?interference.As it combines such two navigation systems as satellite navigation and inertial navigation,it is difficult to implement test and evaluation by using traditional single test methods,and it is required to perform the corresponding research for integrated navi?gation technology.By analyzing integrated navigation mechanism,this paper proposes a compatible test and evaluation method for inte?grated navigation,and designs an integrated navigation test and evaluation system based on simulator for simulation and verification.The basic framework of simulation system is analyzed.This paper uses this system for simulation experiment.The results show that this simu?lator can simulate high?speed carrier with acceleration of 50 g and velocity of 8 km/s.This system can evaluate carrier’s performance and the result is similar with that of practical test.Therefore the simulation system has referential value for integrated navigation terminal test.
